TMS320F28075: 28075 codestart will not fit into available memory and GPIO72 concern

Dear Sir/Madam

I have two issues:

The first：

There is an error about codestart section. it say codestart will not fit memory. cmd file as below:

/* Flash boot address */
BEGIN : origin = 0x080000, length = 0x000002

/* Flash sectors */
FLASHA : origin = 0x080002, length = 0x001FFE /* on-chip Flash */
FLASHB : origin = 0x082000, length = 0x002000 /* on-chip Flash */

I checked the map file as below, codestart failed to allocate, but the .ti_catalog_c2800_initF2837x_begin occupy this memory.

what's the .ti_catalog_c2800_initF2837x_begin , my device is F28075.

currently I changed the cmd file: BEGIN : origin = 0x080000, length = 0x000004  it could link well

output attributes/
section page origin length input sections
-------- ---- ---------- ---------- ----------------
codestart

.ti_catalog_c2800_initF2837x_begin

00080000 00000002 Boot.a28FP : Boot_asm.o28FP (.ti_catalog_c2800_initF2837x_begin)

The second:

I use EMIF, as you known the GPIO72 is both for EM1D12 and Boot mode pin 1.

I connected the GPIO72 with SDRAM. and Pull up GPIO72 and GPIO84 with 2.2k.

it could run well via emulator, but can not run from flash standalone without emulator.

Thanks!

Have a good day!
